How can I unprotect the block protect bit registers BP[2..0] in EPCS or EPCQ configuration devices without using the Altera ASMI Parallel IP?

Description

You can use quartus_jli and a .jam file generated from a .JIC file to unprotect the block protect bits in an EPCS or EPCQ configuration devices. The generated .jam file will contain the appropriate programming algorithm for this procedure. 

Resolution
You can use quartus_jli to execute the optional procedure from the .jam file to unprotect the BP[2..0] registers in the EPCS or EPCQ configuration devices as shown below.

 

If using the quartus_jli executable, the command would be:

quartus_jli –aPROGRAM –eDO_EPCS_UNPROTECT <filename>.jam

 

If using the JAM STAPL player, the command would be:

jam –aPROGRAM – dDO_EPCS_UNPROTECT=1 <filename>.jam

 

The JAM STAPL Byte-Code (JBC) Player uses the same command as above to run a .jbc file, except for the executable name.
